Waffle House America

The map was done by taking USGS 30x60 minute map quad sheets, overlaying them onto Google Earth, and extruding the height based on the number of Waffle Houses. More details and data by quad can be seen at mapsbynik's tumblr site. Atlanta is the home base for the chain so their dominance was expected, however the degree to which it towers above the rest of the country is truly impressive.

USGS quads are not a common unit for this type of mapping (counties
would be much more typical) but the quads work nicely for the
Waffle House data pattern. Because the Atlanta area is spread among numerous counties, a county map would spread the data out. This would result in more of a boring low rise edge city look than the towering skyscraper we get here.
